“This “infomania study” has been the bane of my life. I was hired by H-P for one day to advise on a PR project and had no anticipation of the extent to which it (and my responsibility for it) would get over-hyped in the media.

There were two parts to their “research” (1) a Gallup-type survey of around 1000 people who admitted mis-using their technology in various ways (e.g. answering e-mails and phone calls while in meetings with other people), and (2) a small in-house experiment with 8 subjects (within-S design) showing that their problem solving ability (on matrices type problems) was seriously impaired by incoming e-mails (flashing on their computer screen) and their own mobile phone ringing intermittently (both of which they were instructed to ignore) by comparison with a quiet control condition. This, as you say, is a temporary distraction effect – not a permanent loss of IQ. The equivalences with smoking pot and losing sleep were made by others, against my counsel, and 8 Ss somehow became “80 clinical trials”.

Since then, I’ve been asked these same questions about 20 times per day and it is driving me bonkers.”
